No Known Interaction
Medically reviewed by · Updated July 2026 · Pair last verified Sep 13, 2026
The bottom line No known interaction

We found no known interaction between Hyaluronic Acid and Hydralazine in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.

Hyaluronic Acid and Hydralazine

We checked these two against our interaction database. Here is what we found.

No Known Interaction Found

We did not find a documented interaction between Hydralazine and Hyaluronic Acid in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.

Worth understanding: our licensed dataset holds no drug-interaction record for Hyaluronic Acid at all — not against Hydralazine, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.

If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.

Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Hyaluronic Acid safety at a glance

Hyaluronic Acid overall Use caution Generally well tolerated for most adults, but long-term safety of supplements is not fully studied.
Pregnancy Avoid Not enough safety data; best to avoid oral supplements unless your doctor advises otherwise.
Breastfeeding Avoid Little safety information is available, so avoid oral supplements unless cleared by your doctor.

Safety guidance is general; always confirm with your pharmacist or doctor for your situation.

No Interaction Found — But Data Suggests Hyaluronic Acid and Hydralazine May Share Several of the Same Side Effects

This is not an interaction. Neither one changes how your body handles the other, and nothing here says they react together. What our sources do show is that each has separately been linked to the effects below — so taking both can make those effects more likely to turn up, and harder to pin on one or the other if they do. One of them is worth acting on rather than waiting out — marked below.

  • Bleeding or bruising Worth acting on Additional detail

    Hyaluronic Acid

    “The use of needle-free devices to inject hyaluronic acid for cosmetic purposes has been reported to cause serious injury, and in some cases permanent harm, to the skin, lips, and eyes.

    Topically, hyaluronic acid application has been reported to cause eczema, erythema, itching, wound hemorrhage, and wound infection (e.g., erysipelas).”

From our pharmacist’s overview on the Hydralazine page

“Hydralazine is the drug doctors reach for when blood pressure needs forcing down, so I read this list of 136 supplement interactions with genuine concern rather than routine caution. Start with the four rated major: two are toxic plants with direct effects on the heart and blood vessels, tyramine can push pressure back up and undo the…”

About Hyaluronic Acid

What is Hyaluronic Acid?

  • Skin hydration and aging
  • Joint comfort and osteoarthritis
  • Dry eyes
  • Wound and tissue healing
  • Gum and mouth health

Hyaluronic acid is a natural substance in the body that helps hold water in the skin, joints, and eyes. Oral and topical products are popular for skin moisture and joint comfort, and the evidence is moderate for some uses (like dry eyes and skin hydration) but weaker for others. It is generally well tolerated, but talk to your pharmacist or doctor before starting, especially if you are pregnant or breastfeeding.

Naturally found in skin, joints, and connective tissue; supplements are usually made by bacterial fermentation or from animal sources · Oral capsules, tablets, liquids, topical creams and serums, eye drops, and injectable products (given by professionals)

An interaction check asks whether these two react with each other — it does not ask whether Hyaluronic Acid is a good idea for someone in your situation. Here is what our Hyaluronic Acid record says about it on its own.

Hyaluronic Acid: dosing

There is no single standardized dose of hyaluronic acid that fits everyone, and the right amount depends on the form and how it is used.Oral supplements come in a range of strengths, and topical products and eye drops vary by brand.

Taking Hyaluronic Acid and Hydralazine Together: Common Questions

Is it safe to take Hyaluronic Acid with Hydralazine?
We do not list a known interaction between Hyaluronic Acid and Hydralazine. That does not guarantee the combination is risk-free, so confirm with your pharmacist or doctor — especially if you take other medications or have a health condition.
Do Hyaluronic Acid and Hydralazine have any of the same side effects?
Yes — our sources link each of them separately to 2 of the same effects. That is not an interaction: neither changes how your body handles the other. It does mean that if one of those effects turns up, it can be harder to tell which one is behind it. They are listed on this page with the source behind each.
Does Hydralazine interact with any supplements?
Yes. Hydralazine has documented interactions with 136 supplements in our database — Hyaluronic Acid is not one of them. The Hydralazine interaction page linked on this page lists every one, ranked by severity.
